Updated at 3:55 a.m. Sunday: Revised to include comments from the woman's attorney.

An elderly Tarrant County woman who told police an Uber driver raped her before dropping her off in October is suing the San Francisco company and the Dallas driver for more than $1 million.

Hashem Ramezanpour, 40, is wanted on a charge of aggravated sexual assault. Fort Worth police said he may have fled the country. He is a citizen of Iran, according to court records.

The 77-year-old woman— identified in court records only as "Jane Doe" — said in a lawsuit filed Thursday in Dallas that one of her sons used the Uber app Oct. 22 to get her a ride from a friend's home back to her house.

Ramezanpour picked up the woman in his white 2016 Honda Civic. But instead of driving her home, Ramezanpour took the woman to a secluded wooded area, where he "viciously beat and raped her," according to the suit.

The woman's complaint alleges that lab tests confirmed Ramezanpour as her attacker.

"When Uber placed unsuspecting women such as Mrs. Doe alone inside Hashem Ramezanpour's vehicle, it was like locking visitors at a zoo inside a hungry tiger's cage," the lawsuit reads.

The woman accuses Uber of negligence and said in her complaint that Ramezanpour had a criminal and personal history that should have disqualified him from driving for the company.

Uber says its drivers must undergo background checks before it allows them to use its app.

However, the company has fought efforts that would require it to conduct fingerprint background checks, which many law enforcement experts consider to be more comprehensive. And Uber generally accepts drivers with criminal records as long as they have not been convicted of a felony, violent crime or sexual offense within the last seven years.

"What has been described and reported to police is a violent act no person should ever have to go through, " the ride-hailing company said in a prepared statement. "We are working with law enforcement officials to fully support their investigation. This driver's access was immediately removed from the app, and he has been permanently banned."

Quentin Brogdon, the woman's attorney, said Uber could have prevented the attack.

"To say this was a 'violent act' is an understatement," he said. "She was beaten, bruised and torn in places no woman, no person should be."

What's concerning, Brogdon said, is that Ramezanpour was formally charged with assault in a Dallas County court in March, but was able to continue driving for Uber.

The misdemeanor charge was dismissed on Nov. 3 — 12 days after the reported rape in Tarrant County.

Ramezanpour was arrested in February after a teenage relative complained to Dallas police that he pushed her to the floor and struck her with his hands, court records show.

The teen reluctantly reported the attack to a school counselor, according to a police affidavit. Police officers said they observed bruising around the girl's neck, a cut on her bottom lip, bruising on a leg, scratches on her back and a bump on her forehead.

Ramezanpour admitted to police that he had pushed the girl but said it was to mete out discipline, according to the police affidavit.

A Dallas court tossed the family violence charge after he completed an anger-management course, records show.

A search of Ramezanpour's name in the Texas Department of Public Safety criminal history database shows no convictions in the state.

Brogdon said there's a serious issue with Uber's business practices.

"Given the choice and the information, nobody would willingly entrust their 77-year-old mother to the locked car of a predator with a pending criminal charge for violent assault, regardless of whether there had been a conviction for that charge," Brogdon said.

The 77-year-old woman's suit also appears to reference an allegation by another woman who told the Fort Worth Star-Telegram that Ramezanpour had sought her at her place of work after giving her a ride.

Amanda Leboeuf of Dallas told the newspaper that she used Lyft in March to request a ride from the Wal-Mart where she works and got Ramezanpour. He offered her his personal phone number to use outside of the app, according to her account to the Star-Telegram.

A few weeks later, Ramezanpour came to the store and began talking to her co-workers, Leboeuf told the newspaper. In August, he approached Leboeuf while she stocked shelves. He held a child he identified as his daughter and asked for Leboeuf's number, suggesting they go out to eat or have drinks, according to the Star-Telegram.

Leboeuf said she declined to give him her number but that he called her later that night. She recognized his number and didn't answer.
